Table 2.

The purity and recovery of fucoxanthin from the P. tricornutum biomass obtained by supercritical fluid extraction under 30 MPa and 30 °C at different concentrations of co-solvent conditions.

Co-Solvent (Ethanol, % v/v)	Ethanol + CO₂ (g/min)	Fucoxanthin Purity (mg/g Extract)	Fucoxanthin Recovery (% w/w)
10	3.406	22.06 ± 1.92 ^ab	12.69 ± 1.14 ^a
20	3.208	28.65 ± 0.49 ^b	41.68 ± 0.71 ^b
30	3.002	13.75 ± 0.65 ^a	34.17 ± 1.61 ^b
40	2.801	85.03 ± 7.67 ^c	66.60 ± 6.00 ^c
50	2.591	74.73 ± 2.45 ^c	39.46 ± 1.29 ^b

Different superscripted alphabets (a–c) indicate significant differences (p < 0.05) and the data are expressed as mean ± standard deviation (n = 3, SD ≤ 5%).
